Technical Field
The utility model relates to a machining field refers in particular to an anchor clamps that is used for non-magnetic part plane abrasive machining.
Background
The non-magnetic parts comprise parts such as a silicon carbide plate, a non-magnetic stainless steel plate and the like, and the application relates to the industrial fields of military use, civil use and the like. The surface of a high-performance part usually needs to be ground, but the part cannot be directly fixed on a grinding machine workbench through magnetic force because the part is nonmagnetic. At present, a common fixing mode is that glue is adopted to directly paste a processed workpiece on a workbench, and the mode is difficult to disassemble the workpiece after processing and is not suitable for parts needing double-sided grinding processing; in addition, there is also a non-magnetic grinding fixture designed as the one disclosed in prior art 201220117238.9, in which the longitudinal and transverse blocking irons form a rectangular area, the blank to be processed is arranged in the rectangular area, the corner blocking irons are closely connected with four corners formed by the longitudinal and transverse blocking irons, and the permanent magnetic chucks are respectively attached to the longitudinal, transverse and corner blocking irons and are adsorbed on the surface of the grinding machine table; because the length of the longitudinal stop iron and the length of the transverse stop iron are longer, in order to ensure the positioning precision, the processing requirements of the longitudinal stop iron and the transverse stop iron are higher, and the production cost is greatly increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing a anchor clamps that is used for non-magnetic part plane abrasive machining.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a clamp for grinding the surface of a non-magnetic part comprises a base body positioning seat made of a magnetic material, a workpiece positioning surface positioned at the upper end of the base body positioning seat and used for placing a workpiece, and clamping plates which are respectively arranged on the periphery of the base body positioning seat and are L-shaped and used for fixing the workpiece; each clamping plate comprises a clamping portion horizontally placed at the edge of the workpiece positioning face, and a connecting portion vertically placed and fixed with the side face of the base body positioning seat through a bolt.
Preferably, each side surface of the base body positioning seat is provided with two clamping plates; the two clamping plates are symmetrically arranged along the central line of the base body positioning seat.
Preferably, the workpiece positioning surface is provided with grooves between the two clamping plates and on both sides of the workpiece positioning surface.
Preferably, the height of the clamping portion is less than the thickness of the workpiece.
Preferably, an adjusting block is further arranged between the connecting part and the side face of the base body positioning seat.
Preferably, the base positioning seat is made of cast iron material.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses earlier realize the work piece location through the base member positioning seat, rethread base member positioning seat splint all around are fixed the work piece, and convenient to use, location are accurate, and the contact surface of clamping part and work piece is little, the processing of being convenient for to only clamping part is higher than the work piece locating surface, compares prior art, can the thinner work piece of clamping.

Wherein: 1. a workpiece; 2. a base body positioning seat; 3. a splint; 31. a clamping portion; 32. a connecting portion; 4. a bolt; 5. an adjusting block; 6. a workpiece positioning surface; 7. and (4) a groove.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1-4 show the fixture for grinding the non-magnetic part plane according to the present invention, which comprises a base positioning seat 2 made of cast iron material, a workpiece positioning surface 6 located at the upper end of the base positioning seat 2 for placing a workpiece 1, and a clamping plate 3 respectively disposed around the base positioning seat 2 and in an L shape for fixing the workpiece 1; each clamping plate 3 comprises a clamping part 31 horizontally placed at the edge of the workpiece positioning surface 6 and a connecting part 32 vertically placed and fixed with the side surface of the base positioning seat 2 through a bolt 4; when in work: the base body positioning seat 2 is placed on a grinding machine workbench firstly, then the base body positioning seat 2 is fixed by electrifying a magnet of the workbench, then the workpiece 1 is placed on the base body positioning seat 2 to be positioned, then the bolts 4 around the base body positioning seat 2 are rotated, the clamping plate 3 is driven to be fixed, the clamping part 31 is attached to the workpiece positioning face 6 at the moment, clamping is achieved, wherein the workpiece positioning face 6 needs to guarantee higher flatness, and the tolerance grade is IT3 grade.
Furthermore, two clamping plates 3 are arranged on each side surface of the base body positioning seat 2; two splint 3 are placed along the central line symmetry of base member positioning seat 2 for the clamping is more firm.
Further, the workpiece positioning surface 6 is provided with the grooves 7 between the two clamping plates 3 and on two sides of the clamping plates respectively, the contact area between the workpiece positioning surface 6 and the workpiece 1 can be reduced by arranging the grooves 7, meanwhile, the processing requirement of the workpiece positioning surface 6 can be reduced, and the production cost is reduced.
Further, the height of the clamping part 31 is smaller than the thickness of the workpiece 1, so that the workpiece 1 can be ground at one time.
Further, an adjusting block 5 is arranged between the connecting portion 32 and the side surface of the base positioning seat 2, wherein the adjusting block 5 has various thicknesses and can be replaced according to the size of the workpiece 1.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
